PLATE CXVni. 
The rays of the first dorsal fin are bony, serrated anteriorly, and 
eight in number ; the second dorsal fin contains twenty soft rays ; 
the pectoral fin twelve, ventral nine, anal eighteen, and caudal 
eighteen. The dentated tubular processes into which the front of 
the head is elongated, forms a striking character of this fish ; it may 
be also added, that neither of the other British species of Gurnards 
have the gill-covcrs armed with spines of such considerable strength 
^nd size as the Piper.
